Tested with AMD Radeon Pro WX 9100, where it brings performance back to 2.80 level, and combined with recent changes is about 2-15% faster than 2.80 in our benchmark scenes. This somehow appears to specifically address the issue where adding more shader nodes leads to slower runtime. I found no additional speedup by applying this to change to 2.80 or removing the new shader node code. Ref T71479 Patch by Jeroen Bakker. Differential Revision: https://developer.blender.org/D6252
